Seperation of Mixtures

Our Equipment

What did we do?

Our purpose was to see if mass changies if you seperate substances from a mixture.

Our results were that the mass of the Our lab was very successful because the substances decresed. The mixture we had started out as 55.78 which changed after the experiment to 28.57 this was very similer to the other substances. To sum this up we really enjoyed this lab and how me and my partner worked very well together.

1. Wrap a magnet in plastic lunch wrap and move it through the mixture of the three solids. The iron filings will stick to the magnet. The filings can be removed by unwrapping the plastic from the magnet carefully.2. Mix the remaining salt and sand in water and stir. Make sure you have used enough water to dissolve all of the salt, but not too much that handling large quantities of salt water becomes a problem.3. Using a funnel, flask and filter paper, filter off the sand from the salt water solution. Wash the sand with some fresh water to remove the last of the salt from the sand in the filter paper.4. Put the sand to one side and allow it to dry in the Sun or warm oven.5. Collect all the salt water in a weighed container and evaporate off the water. This may take some time in the Sun or may be sped up in an oven.6. Weigh each of the separated solids and compare them with their original weights. Give a prize for the best set of results.
